In this work, we exploited the step-wise target controllability framework [1]}, which relies on a lti dynamics and is based on the Kalman rank condition.
While it is known that the brain presents a nonlinear dynamics, the study of linear models has proved to be beneficial in improving our understanding [2]}, [3]}, [4]}.
Specifically, the controllability of a linearized model can inform on the controllability of the nonlinear model [5]}.
